Where must the current empty weight and CG records be kept?

• A. In the maintenance manual.
• B. In the aircraft flight manual or weight and balance records required by 14 CFR § 23.1583.
• C. In the logbook only.
• D. On the exterior placards.

Answer: (B)

Keep the current empty weight and center of gravity data with the aircraft’s official weight and balance records so the flight crew can easily access up-to-date loading information. This requirement comes from 14 CFR 23.1583, which specifies that weight and balance data, including the current empty weight and CG, must be maintained in the aircraft flight manual or in the weight and balance records that accompany the aircraft. Having these records in the flight manual or a dedicated weight and balance file ensures they’re readily available for accurate takeoff and load planning, and that any changes after modifications are properly reflected. Placing them only in the logbook or on exterior placards doesn’t provide the required, readily accessible reference for flight planning.
